Claims

A memory unit for storing information about the cartridge;
A substrate having the memory part and an electrical contact;
A support portion for supporting the substrate with the electrical contacts exposed;
A first movement restricting portion that is flexible and restricts movement of the substrate by the support portion; and a second movement restricting portion that restricts movement of the substrate. The movement restriction direction for restricting the movement of the substrate by the movement restriction portion is the same as the movement restriction direction by the first movement restriction portion, and the movement restriction for restricting the movement of the substrate by the second movement restriction portion. The cartridge is characterized in that the distance is shorter or the same as the movement restriction distance by the first movement restriction unit.

The cartridge according to claim 1, wherein the first movement restricting portion is movable in a height direction of the substrate.

The cartridge according to claim 1, wherein the first movement restricting portion has a claw portion.

The cartridge according to any one of claims 1 to 3, wherein the first movement restricting portion includes a beam extending in the movement restricting direction.

The cartridge according to any one of claims 1 to 4, wherein the support portion and the first movement restricting portion are made of the same material.

The cartridge according to any one of claims 1 to 5, wherein the second movement restricting portion is a frame body of the cartridge.

The cartridge according to claim 1, wherein the electrical contact is provided at an end portion of the cartridge in a longitudinal direction.

8. The cartridge according to claim 1, wherein the electrical contact is provided on a frame having an electrophotographic photosensitive member.

A main body electrical contact that is electrically connected to the electrical contact of the cartridge according to any one of claims 1 to 8,
And a control unit that reads out information stored in the memory unit via the main body electrical contact.

A process cartridge that is detachable from an image forming apparatus having a main body electrical contact, the memory storing information relating to the process cartridge;
A cartridge electrical contact electrically connectable to the body electrical contact;
A cartridge contact support for supporting the memory at a support position;
When the direction in which the memory is inserted into the support position is the insertion direction, the thickness direction of the memory is the height direction, and the insertion direction and the direction orthogonal to the height direction are the horizontal direction,
The cartridge contact support portion includes an opening for inserting the memory into the support position, a horizontal direction restriction portion for restricting movement of the memory mounted at the support position in the horizontal direction, and the support position. A height direction restricting portion that restricts movement of the mounted memory in the height direction;
A flexible temporary fixing portion that passes through the opening and temporarily restricts movement of the memory mounted at the support position in the insertion direction;
A process cartridge comprising: a stop portion for finally restricting movement of the memory in the insertion direction.

The process cartridge includes a first frame body having the support portion;
A second frame coupled to the first frame,
The process cartridge according to claim 10, wherein the second frame body is disposed in an insertion direction with respect to the first frame body.

The stop portion for finally restricting movement of the memory in the insertion direction is provided on a side of the memory substrate facing the cartridge electrical contact side in the height direction. The process cartridge according to 11.

An image forming apparatus in which a process cartridge is detachable and forms an image on a recording medium,
A process cartridge according to any one of claims 10 to 12, and
A main body guide portion for guiding the process cartridge for mounting;
An image forming apparatus comprising: a main body electrical contact electrically connectable with the cartridge electrical contact of the process cartridge.

A cartridge manufacturing method comprising:
A memory unit for storing information on the cartridge, a substrate having the memory unit and having an electrical contact, a support unit for supporting the substrate in a state where the electrical contact is exposed, and flexible. And a second movement restricting portion for restricting the movement of the substrate by welding with respect to a frame having a first movement restricting portion for restricting the movement of the substrate by the support portion. A method for producing a cartridge, comprising a step.

The method of manufacturing a cartridge according to claim 14, wherein the frame has a protrusion, and the protrusion is deformed into a second movement restricting portion by welding.

The method of manufacturing a cartridge according to claim 15, wherein the first movement restricting portion is transformed into a second movement restricting portion by welding.
